1. An information-presentation (“

  • IP”

    ) structure comprising an object-impact (“

    OI”

    ) structure having an exposed surface for being impacted by an object during an activity, the OI structure comprising a variable-color (“

    VC”

    ) region which extends to the exposed surface at a surface zone and normally appears along it largely as a principal color during the activity, an impact-dependent (“

    ID”

    ) of the VC region responding to the object impacting the surface zone at an ID object-contact (“

    OC”

    ) area spanning where the object contacts the surface zone by temporarily appearing along an ID print area of the surface zone largely as changed color materially different from the principal color if the impact meets threshold impact criteria, the OC area being capable of being of substantially arbitrary shape, the print area at least partly encompassing, at least mostly outwardly conforming largely to, and being largely concentric with the OC area, the principal and changed colors also differing materially as generally viewed by persons having color vision deficiencies comprising dichromacy and anomalous trichromacy.
